This project deals with the processing of primary metals such as aluminum alloys. Liquid metals are employed as cathodes in molten salt electrolysis. The cathodic part is reduced into the molten metal, e.g. aluminum into the aluminum pad of Hall-Heroult cells or into the floating aluminum laser of a three layer aluminum refining cell. In this work metals that are normally solid will be reduced into and onto liquid metal substrates, both at ambient temperatures and in molten salt systems at elevated temperature. Electrolytic reduction of metals from aqueous solution at mercury and amalgam electrodes will also be studied and extended to cover low-melting metal mixtures and gallium in non aqueous media. The metal deposition at liquid silver and aluminum, using the established see- in technique, will also be studied. The research conducted includes a study of the nature of solid products electrocystallized on an atomically smooth substrate and the establishment of the conditions under which alloying or film deposition occurs.

这个项目涉及诸如铝合金等原金属的加工。液态金属在熔盐电解中用作阴极。阴极部分被还原成熔融金属，例如铝进入Hall-Heroult电解槽的铝垫或进入三层铝精炼电解槽的浮动铝激光器。在这种工作中，通常是固体的金属在环境温度下和在高温下的熔盐系统中都会被还原成液态金属基底。还将研究在汞和银汞合金电极上从水溶液中电解还原金属，并将其扩展到非水介质中的低熔点金属混合物和镓。利用已建立的see- in技术，还将研究金属在液态银和铝上的沉积。所进行的研究包括研究在原子光滑的衬底上电结晶的固体产品的性质，以及建立合金或薄膜沉积发生的条件。
